i Application filed August 19, 1903.

I all. who-m. at mayconcern:

-Be it known that we, WILLIAM MARRS and THOMAS J. WOLF, citizens of the United States, residing at De Queen, in the county of Sevier and State of Arkansas, have invented a new and useful Agricultural. Boiler, of, which.

the following is aspecification.- This inventio relates" l I ncuatiaiboiiers; and it has'for its object to provide a device of this class which,lwhile adapted to avariety of purposes requiring hot water, such as cooking feed for the fattening of cattle, and for other similar purposes, shall be especially adapted for the purpose of preparing and putting up fruit, vegetables, and the like.

In agricultural communities, and especially f in the fruit-growing sections of the country,

immense quantities of valuable fruits are. an-

nually wasted on account of the inability ofv the farmer to market them or to convey them in season to the. canneries. .A considerable proportion of such wastage might be saved if the farmer were in aposition himself to can and preserve such fruits and vegetables as cannot otherwise be well disposed of. It is to provide a convenient and inexpensive appa-. ratus through the medium of which this result may be accomplished that our invention is aimed; and it has for its object to provide a device of this class which shall possess su-- perior advantages inpoint of simplicity, du-

rability, and general efiiciency.

With these and other ends in view theinvention consists in the improved construction, 3S

arrangement, and combination of parts which will be hereinafter fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure l is a longitudinal sectionalview of a-device constructed in accordance .with the principles of our invention. V Fig. 2 is a, verticaltransverse sectional view taken on the line '2 2 of Fig. 1.

Corresponding parts in both figures are indicated by similar characters of reference.

The casing l, which constitutes the'furnace member of our improved, device, consists mainly of a rectangular box which may be constructed of sheet metal and which is supported at itscorners upon legs 2, elevating it a suitable distance above'the ground. The

serial ,093. (No modelJ front end 3-of the box or casing is provided with a door 4:, through which fuelmay be fed into the combustion-chamber, which latter is provided with alining 5, composed ofa sheet of metal suitably curved, as clearly shownin Fig. %"of the drawings. 'The front lining plate 7 is disposed against the rear wall of the furnace-chamber, said lining-plate be- 1 v ing provided with flanges 8, abutting againstsaid rearwall, thereby forming an air-space j'e'iid 3 of the casing has' a curved upper'edge' (designated 6) to support the-front end of the tank, as will be presently'deseribed. A.

which serves to prevent the waste ofheat by radiation and which also prevents the-said rear wall from burning out. The objectof making the lining-plate 5 in the curved: shape illustrated in Fig. 2 is likewise not only to protect the casing, but to prevent the loss of heat through radiation from the 'spaces lll at the corners of the casing. The rear endof the casing is provided with an upwardlyextending flange 1-1, engaging a lip 12 upon I the rear end of the tank, which is designated 13. Said tank, which is mainlyrectangular in shape, has a semicylindrical bottom 14;, the curvature of which conforms to that ofthe frontwall 3 of the furnace-casing, upon the upper edge of which the said tank has a partial support, additional supports being provided-by the lip engaging the flange 11 and by longitudinal lips 15 upon either side of the tank engaging the upper edges of, thesides of the casing, as will he. clearly seen in Fig.2,

The semicylindrical lower portion of the tank is provided at the front,end p thereof with an extension 16, forming smoke-arch, from which a chimney or s ck 17 extends upwardly, as showm'said smoke archer cham-- ber beingprovided at its front/end with a and through which access may be had tdthe flues 20, which extend longitudinally through ter.

the furnace-casing to permit products of COl'D'.

ascend, pass forwardly through the flues 20, and up through the stack or exit 17. The

bustion from thefuel placed in the burners to door 18, hinged at its upper edge, as at 19,

v be easily transported when it is desired to of time and fuel than would otherwise be the case. used in a general way as a water-heater for a of wavsiwhich will readily suggest themselves q sides of the tank are provided at their upper edges with upwardly-extending standards 25, arranged in pairs on opposite sides and provided each with a plurality of notches 21, adapted to receive transverse rods 22,.connected with thebails 23 of the capsupporting baskets 24, which latter may thus be supported by the standards 25 at various elevations within the water-tank. The baskets 24 are provided ith openings 26 to permit the" wafor to circulate. freely, or they. may be constructed of wire netting or other-suitable foraminousmaterial. Therods 22 are provided at their extended ends with handles 28, by means of which they may be conveniently manipulated. i

'lhe operation and advantages of this invention will be readily understood from the foregoing deseriptiox i, taken in connection with the drawings hereto annexed. The tank and the furnace-casing are separable and may thus move the machine, which is usually employed out of doors, from one place to another. 'At the same time the parts of the device are adapt ed to be connected conveniently and without danger of leakage of either smoke or water. The arrmigement of the lines extending through the tank or eaten-heater increases the elliciency of the device and permits the water to be raised to boiling heat with'less expense lt is obvious that the device maybe variety of purposes; but when it is used-"for the purpose of canning fruit or vegetables, which is the primary object of the invention, the'eansare disposed within the rectangular portion of the tank, being supported upon the loiveymost notches of the standards 25. When the contents of the cans have been sulliciently cooked, the containing-baskets may be raised. to the second notch while the air is being exhausted from the cans, and finally to the third notclnwhere they are supported while the vent-openings are being closed.

This device may be employed in a variety to those skilled in the art to hieh it appertains. lt may also be stated that with regard to the precise structural details of the device I we doubt limit ourselves, but reserve the right to any changes andanodllications which may be resorted to \VItlIOUlZ departing fronrthe spirit and scope of our invention orsacrificing the utility of the same.

Having thus described our invention, we claim- 5 1. Ina device of the class'describerl, a rectangular furnace-casing havi ng the upper edge of its front endcut off to form a segmentalreeess, and provided at itsrear-end'with anupwardly-extending flange, in combination witlr a tank providedwith lips at its sides and rear end, said hps'engagmgtheupperedges of the sides and the flangeat the rear end of the su )por'ted upon the casing and havinga semi- ,cy indrical bottom," flues extending therethrough, a smoke-chamber at 1ts front end and an exit-pipe rising from said smoke-chamber.

3. In a device of the elassdescrihed, the combination with afurnacc-casing having a vertical flangenearits rear end and a recess at its front end, of a detachable tank resting at its ,front end in said recess and provided at its sides and rear end with lips engaging the sides ofthe furnace-casing andthe flange at the rear end of the latter, said tank being provided with flues extending therethrough and at its front-end with a smoke-chamber havmg a hinged door and an upwardly-extending exltpipe.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
